Honeywell 51196694-310 Keyboard with Trackball

The Honeywell 51196694-310, also cataloged as the 51196694-310 Keyboard with Trackball, operates as a dedicated hardware component for operator interface and process control execution within Experion PKS system platforms.

Hardware Specifications

Process Control and DCS Characteristics

• 4-20 mA HART loop protocol: The input device facilitates the human-machine interface (HMI) interaction required for monitoring HART-enabled device diagnostics and configuration parameters via the workstation.
• FOUNDATION Fieldbus / Profibus PA connectivity: The interface supports workstation-level interaction with fieldbus segment commissioning tools, allowing operators to execute navigation and data entry for digital bus management.
• Channel-to-channel isolation: The USB interface utilizes standard electrical isolation to protect the workstation's internal bus from static discharge or transients originating from the operator's workspace environment.
• Cold junction compensation (CJC): The keyboard assembly is designed to maintain functional stability in environments where sensitive analog measurement instrumentation, such as CJC-dependent temperature inputs, is simultaneously monitored at the console.

Frequently Asked Questions

Q: Can the keyboard be cleaned with industrial detergents?

A: The IP65 rating provides protection against dust and water ingress. Use a damp cloth with non-abrasive, industrial-grade cleaners. Ensure the USB connector is shielded from liquid exposure during cleaning.

Q: Are the programmable keys restricted to specific HMI functions?

A: The keys are designed for customization within the Experion PKS environment. Refer to the system configuration manual for assigning specific control tasks to the programmable inputs.

Field Installation Guidelines

• Mounting: Secure the device on a stable console or desk surface. Given the 1.5 kg weight, ensure the mounting surface provides adequate friction to prevent movement during high-frequency navigation tasks.
• Grounding: While the device is USB-powered, ensure the workstation cabinet is bonded to the cabinet protective earth (PE) bus. A solid ground reference is necessary to mitigate electrostatic discharge (ESD) during operator interaction.
• Wiring: Route the USB cable through protected pathways within the operator console. Maintain physical separation from high-voltage AC lines to prevent induced electromagnetic interference that could affect trackball cursor stability.
